You do: 1/2 job/hr
Your friend does: 1/3 job/hr
Together: (1/2 + 1/3) job / hr
= (3/6 + 2/6) job/hr
= 5/6 job/hr .
Since you do 5/6 job/hr, the corresponding
inverse unit rate is
6/5 hr/job
= 1 and 1/5 hr/job
= 1.2 hours/job
= 1 hour 12 minutes per job.
4 = -0.8n
To find n divide both sides by -0.8:
n = 4 / -0.8
n = -5
V = 7 x 4 x 15 = 420 inches^3
Answer: See explanation
Step-by-step explanation:
Total water fetched = 24 pints.
Jill drank a tenth of this. This will be:
= 1/10 × 24
= 2.4 pints
Jack drank a quarter. This will be:
= 1/4 × 24 = 6.
They gave three eighths to dame Dob . Thus will be:
= 3/8 × 24
= 9
They gave a fifth to jill's mother. This will be:
= 1/5 × 24.
= 4.80
Amount that'll be left over will be:
= 24 - (2.40 + 6 + 9 + 4.80)
= 24 - 22.2
= 1.8
1.8 pints of water will be left over.
